5.5 Reclamation Performance Standards
5.5.1 Establishing Post - Mining Use
Post - mining use of the land is anticipated to be f r housing development and below grade
reservoirs and graded areas revegetated and returned to property owners.
There will be no Substituted Land to be reclaimed, as defined in Rule 3.1.2.
Mining reclamation is expected to be completed as proposed in the design plan within the
five year timeframe required in Rule 3.1.3. The anticipated schedule indicates slope liner
completion and pit backfill within approximately X8-24 months.
5.5.2 Public Use
Design of the reclaimed reservoir slope liners i�has not anticipated €e - public recreational
use of the lined reservoirs. The crest of the slope liners is designed to slope approximately
2% into the reservoirs.

5.5.3 Reclamation Measures — Material Handling
Approximate final site grading at the Three Bells Mine is anticipated to occur according to
the following:
3:1 (FIN) — Reclaimed, lined reservoir slopes
2% — Lined reservoir crest
0 -5% — Typical reclaimed land slope
All site grading will comply with CO SEO requirements for stable slope reclamation.
Maximum reclaimed slope will be 3:1 (FIN). Reclamation grading measures will comply
with all local and state erosion prevention measures. Local areas will be stabilized for erosion
control as needed.
Areas to be backfilled (parts of Phase 4, Phase 5, Ditullio Property) will be compacted to
adequate compaction for stability.
